Abstract

The invention provides a method for purification of hydroxylamine so as to have a substantial reduction of cations and anions. The method involves passing a solution of hydroxylamine through at least one strong acid ion exchange bed which has been pretreated with dilute hydrochloric acid and then through at least one strong base anion exchange resin bed.
